Although metalayer selection is constructed from stylus
input points, it can sometimes cross the screen bounds.

For example, when a horizontal stroke is recognized, its
bounding rectangle is inflated to guarantee minimal
height and generally be closer to the visual image of
the stroke.

This patch introduces necessary clipping to make sure
that clients do not have to do that.
